Sequency, frequency, code or time? [DS-SS diversity systems]

This paper presents novel results from computer simulations for different hybrid multiplexing direct sequence spread spectrum systems operation in an indoor wireless environment. Prominent hybrid multiplexing direct sequence spread spectrum proposals using code, frequency and time diversity approaches have been analysed and compared to novel approaches proposed by the authors using sequency diversity. The results in this paper have shown that under certain practical wireless scenarios, the proposed sequency majority multiplexing direct sequence spread spectrum schemes exhibit very significant improvements over the compared current prominent hybrid multiplexing multiple access schemes.
